"Streptococcal" refers to a group of bacteria known as Streptococcus, which can cause various infections in humans. These bacteria are classified into different groups based on their characteristics, with Group A and Group B being the most notable. Infections caused by streptococci can range from mild illnesses, like strep throat, to more severe conditions, such as pneumonia or skin infections. Streptococcal infections are typically spread through respiratory droplets or direct contact with infected wounds. Symptoms can vary depending on the type of infection but often include sore throat, fever, and swelling. Treatment usually involves antibiotics, which are effective in eliminating the bacteria and preventing complications.
